This has been problematic for me in Ubuntu since I live in the UK but want the week to start on a Sunday (because that is the system my work use). I've faffed about in the last couple of versions of Ubuntu to no avail (it changes in Evolution but not on the desktop calendar etc.) and don't want to be editing locale files.

I understand it's probably an issue with GNOME so are there any plans to implement it with Unity? I find it baffling that an operating system doesn't have such a simple option that even my phones always seem to have had.
